I get calls from this number.  No one talks but there is background noise.  How can I stop them?

Caller (man) said I had won a prize package and I should go to Woodbridge to pick it up. The prize was from a ballot filled out in June 2007, did I remember filling it out for RCA, it's a big company, I must have heard of it.

I asked why I would go to Woodbridge just because some guy phones - he claims to be Robert Fiddleton (sp?!), President of the company, phoning long distance from Buffalo (duh - my call display said (416) 360-4084) and there was obvious noise of a call centre in the background. I don't own anything made my RCA, duh...hung up on him.

Found this number on my Caller ID box when I got home today from work.  They didn't leave a message

called and left no messeage.....returned call...out of service...bunch of turds.....

Looking at this site I'm half afraid the voice-mail is a way to collect messages or info through registrations on this site.  Or to get people to sign in on this site.I got someone babbling in a language other than English or French, possibly middle-eastern, punctuated by bouts of giggling.  Male voice.  I didn't listen to the whole thing, but it was apparently 54 minutes and supposedly came some time after 2pm.  I'm in Toronto.  I assumed it would be a local call.  May be a cell since it wasn't on 411.I hope somebody nails these idiots.  But then we also live in a world where laws against credit card fraud and identity theft are under reported.
